DEVICE FOR SAMPLING ORES.

SPECTFICATION forming part of Letters Patent No. 454,120, dated June 16,1891. Application filed Jctober 13, 1890. Serial No. 368,018. (Nomodel.)

To all whom it may concern.-

Be it known that I, DAVID W. BRUNTON, a subject of the Queen of GreatBritain, having declared my intention to become a United States citizen,residing at Aspen, in the county of Pitkin and State of Colorado, haveinvented a new and useful Device for Sampling Ores, of which thefollowing is a specification.

My invention relates to that class of devices or apparatus employed intaking from a large quantity of ore a small portion which shall be anaccurate sample of the whole, and maybe substantially described asfollows:

Referring to the accompanying drawing, A is a handle; B, a blade ortray, made, preferably, of steel, upon the under side of which are theraised sides 0 O and the central partitions D D. The two partitions I) Dare connected at the handle end with the closed curved backE, to whichis attached thewooden handle A. I

To sample a lot of crushed ore, the device is used as follows: The bladeor tray is pushed into the ore until the spaces B B and F are partiallyfilled, when it is lifted and drawn back' simultaneously with agradually-increasing speed until near the side of the operator, when itsbackward motion is suddenly arrested and the apparatus thrust rapidlyforward, while the extreme end of the handle is'slightly depressed. Thiscauses the ore in the compartments B B to shoot out over the back of theblade while the portion of ore in the compartment F is retained thereinby the curved back E, from whence it is discharged by arresting theforward thrust of the blade, by which operation the ore contained in thecompartment F is deposited in a separate pile and at a considerabledistance from that ejected from the compartments B B. After the originallot has been divided in this manner the pile resulting from thedischarge from the compartment F is subjected to the same operation,which is repeated until the result ant sample is small enough for thepurpose for which it is intended.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

The combination of a handle and blade provided with raised sides andpartitions dividing the upper surface of the blade into two or morecompartments, one or more of which are closed at one end, or so arrangedthat the ore upon the blade may be divided into two or more separate anddistinct portions.
